Sika Sikaflex Ultra 310ml Cartridge 255
Sikaflex®-255 Ultra is a cold applied windscreen adhesive, optimized for manual application. It provides a long open time and ensures safe application even under warm conditions. Sikaflex®-255 Ultra is compatible with Sika's Black Primerless and All Black processes and may also be used as a primerless to glass adhesive in auto glass replacement applications. Note: Primerless to glass application requires the glass to be prepared using an Automotive grade glass cleaner such as Sika® Cleaner G+P. The bonding surfaces must be free of contamination and have sufficient UV protection.
